The place where we market our calves will always ask if they have been preconditioned. We have never preconditioned our calves, we usually wean them on the trailer. Preconditioned calves have always brought a little more in the ring, but not enough to make it worth my while. This year, the difference in PC calves versus non PC calves is even greater, so I looked into it again. I still can't make the numbers work out in my favor. The money I spend on feed and shots is more than what I will make back in the ring. (We grow our own hay, but I still figure that feed is a cost.) Plus, if I also figure my labor in there, which I also feel is a cost, I am taking it in the shorts by preconditioning my calves. The only ones who really profit in my eyes, are the feedlots, as they get a healthier calf with minimal weight loss because they have been weaned already. And, they get a PC calf using my labor for free. Preconditioning works for some folks I guess, and Im certainly not saying anyone is wrong for doing it. But here, it is spending money so someone else can have a higher profit.
